Have you been wanting to take a look at Underfoot? Now's your chance, as all subscribers -- both current and inactive -- are being treated to a free three-day trial of the expansion until March 12th. If you decide you like it, purchase it from the Station Store for a discounted price of $34.99 until March 31st. Sony Online Entertainment is offering 500 Station Cash, a Legends of Norrath Loot Scenario and the Mark of Brell in-game item with the offer as well, so it's definitely worth it.
If you've already purchased the expansion, don't worry, SOE isn't leaving you out. Just log in before March 31st to receive an exclusive Gnomework Mercenary skin of your very own!
